Gj. Balas et al., CONTROL OF THE F-14 AIRCRAFT LATERAL-DIRECTIONAL AXIS DURING POWERED APPROACH, Journal of guidance, control, and dynamics, 21(6), 1998, pp. 899-908
The design of linear controllers for the F-14 aircraft lateral-directi
onal axis during powered approach using the structured singular-value
(mu) framework is presented. Controllers are designed for an angle of
attack of 10.5 deg and an airspeed of 137 kn, the on-speed flight cond
ition, Each controller is implemented in a simplified nonlinear simula
tion and the full-order Fortran nonlinear simulation of the F-14, Pilo
t-in-the-loop simulations are used to verify their performance in the
crewed flight simulator at the U.S. Naval Air Warfare Center, Patuxent
River, Maryland, The mu controllers out perform the current analog an
d newly developed digital lateral-directional powered approach flight
control system in pilot-in-the-loop simulations.
